Backbone Router. The ROUTER-LL provides LonTalk routing capabilities between LonWorks twisted pair media and Ethernet. As shown in Figure 1, the ROUTER-LL allows an IP network to be used as a backbone to con- nect LonWorks subnets together. IP Network...
System Requirements To use the ROUTER-LL you need: • A VT100 or ANSI compatible terminal. For example, this can be a stand-alone terminal, or an IBM compatible computer with a serial port and the TERMINAL.EXE or HYPERTERMINAL.EXE application (these come with the standard Windows 3.1 or Windows 95/NT installation respectively).
10BASE-T twisted-pair RJ-45 connector and a 10BASE2 thin coax BNC connector. Power Switch Power is applied to the ROUTER-LL when the power switch is in the on (|) position. Power Connector The ROUTER-LL uses a universal input AC power supply. Use the supplied power cable to connect the ROUTER-LL to any AC power outlet.
232 asynchronous serial communications at 9600 baud, 8 data bits, 1 stop bit, no parity, and no flow control. Establish Communications Connect the power cord between the ROUTER-LL and an AC outlet and flip the power switch to the on (|) position. The green POWER LED should turn on.

NET connector on the ROUTER-LL. Be sure that you configured the ROUTER-LL for the correct transceiver type in the previous step. After a minute or two, the ROUTER-LL will connect to all the other ROUTER-LLs that share the same SERVER. The Connections line indi- cates how many connections exists to other ROUTER-LLs.
ROUTER-LL with full LonWorks Router functionality. Rout- ers connect two communications channels and route LonTalk messages between them. In a ROUTER-LL, one of these channels is always a IP Channel. The other channel can be either TP/FT-10, TP/XF-78, or TP/XF- 1250.
(see Routing Algorithm, below). The domain table entries in the ROUTER-LL are typically set by the net- work services tool during network configuration. ROUTER-LLs are deliv- ered from the factory with the table entries set as described in Appendix C: Factory Setting.
Module, the router may be unable to communicate through its transceiv- ers. The communications parameters for the LonTalk side of the ROUTER-LL are hard coded to the correct values. If these values are set incorrectly by a network services tool, they will be reset the next time the ROUTER-LL is power cycled.
Output Network Buffers. If the total number of bytes for these buffers exceeds 1254, the ROUTER-LL will not function correctly. The counts and sizes of message buffers in the ROUTER-LL are typically configured in the network services tool and set when the router is installed.
Network Buffer counts are always set to 2. Routing Algorithm The ROUTER-LL can use one of four routing algorithms: configured router, learning router, bridge, or repeater. See the LonWorks Router User’s Guide for a complete discussion of the different algorithms. ROUTER-LLs are deliv- ered from the factory configured as repeaters.

Appendix D: RTR_CFG.EXE. Note that each time the communications parameters are set in a ROUTER-LL with a network services tool, they must be reset with RTR_CFG.EXE. This typically happens when installing or replacing a ROUTER-LL, but depending on the network services tool being used, this...
ROUTER-LL will be active. The choices for this field are 10BASE-T and 10BASE2. • IP Address: This is the IP address of the ROUTER-LL on the IP net- work. This addresses should be obtained from your System Adminis- trator.
IP Address Configuration Screen During normal operation, the IP ADDRESS CONFIGURATION screen shows the status and current configuration of the ROUTER-LL. The Connections line indicates how many connections exist to other ROUTER-LLs. The configuration parameters are explained in the Setup Screen section above.
The actual parameters set by RTR_CFG.EXE will be different. Parameters specified as “Configurable” may be changed by a network services tool. Transceiver ID Media Coactive ROUTER-LL Neuron Chip to Transceiver Interface Special Purpose Interface Bit Rate 1.25Mbps Input Clock...

• For low-speed LAN connections with many routers or low band- width segments (e.g. dialup or ISDN), use 1000 bps for Network Bit Rate and 3.0 bits (1100 microsec) for Receive Start Delay. • For Internet connections, use 300 bps for Network Bit Rate and 0.9 bits (1100 microsec) for Receive Start Delay.
Configuring Communications Parameters The ‘c’ and ‘C’ options configure the communications parameters of the Special Purpose mode transceiver on the IP side of a ROUTER-LL. This operation should be performed after a ROUTER-LL is installed by a net- work services tool. If RTR_CFG.EXE is communicating to the ROUTER- LL through the LonTalk side of the router, the far side should be config-...
Appendix E: LonBuilder Installation This section describes the steps needed to install a ROUTER-LL into your LonWorks network using Echelon’s LonBuilder Developer’s Workbench. See the LonBuilder User’s Guide (078-0001-01 Revision 3, Echelon Corp.) for complete details on router installation. Define the IP Channel From the Navigator window, select Network and then Channel.

A). If RTR_CFG.EXE is generating the message, it most likely means that the wrong side was selected to configure. If RTR_CFG.EXE is communi- cating to the ROUTER-LL through the LonTalk side of the router, the far side should be configured. If RTR_CFG.EXE is communicating to the ROUTER-LL through the IP side of the router, the near side should be configured.
Appendix F: LonMaker Installation This section describes the steps needed to install the ROUTER-LL into your LonWorks network using Echelon’s LonMaker Installation Tool. See the LonManager Profiler Users Guide (078-0022-01B, Echelon Corp.) and the LonManager LonMaker Installation Tool Users Guide (078-0023-01B, Echelon Corp.) for complete details on router installation.
